hilt Stove Company, Inc., Maspeth, land, N. Ya corporation of New York Appucaaon sepmbera, 193s, semi No. sans s claims. (c1. 12s- 191) 'This invention l relates to' hinge constructions and more particularly to ahinge and support for oven doors and the like. v

An' object of the invention is to provide an` or the like.

A feature of the invention relates to an oven door having a hinge structure whereby the door is fastened to the body of the Vstove or range entirely by readily removable links, thus avoiding the use of screws and bolts which as is wellknown tend to rust orcorrode rendering it dimcult eventually to remove thedoor.

Another feature relates to an oven door having an improved hinge structure and latch support wherein the sheet metal cover acts to lockthe hinge. plntles in place.

A' further feature relates toran improved form of hinge pintlefor an oven door hinge.

A still further feature relates to the novel organization,` arrangement and relative location of parts which go to make up an improvedand simple hinge and support for oven doors and the like. Y

Other features and advantages not specically enumerated will -be apparent after a consideration of the following detailed description andthe appended claims. I

In the drawing, Fig. 1 is a plan view, partly sectional, of part of a stove and oven door ern-V bodying features of the invention.

Fig. 2 is a left-hand elevational view of Fig. 1. Fig. 3 is a sectional view of Fig. l taken along the line 3-3 thereof.

Fig. 4 is a sectional view of Fig. 1 taken along the line 4 4 thereof.' I Fig. 5 is a detail view of part of the door construction. y

Inasmuch as the hinge and supporting'structure is duplicated at both sides of the door, only one hinge and latch support is illustrated in the drawing. Accordingly referring to Fig. 1 the numeral I represents the usual vertical angle iron forming part of the usual oven door frame, it,

being understood that a similar angle iron is provided at the left-hand end of the door frame.

- The two vertical angle members are connected the frame of the stove to enclose the sides thereof. Fastened in any suitable manner, for example by rivets 4, to the horizontal frame member 2, is a metal bracket 3 having an integral arm 6 bent at right angles'and passing through the aperture 'I in member 2, itv being understood that a similar bracket is provided at the left-hand end of the member 2. The forward end of each arm l 5 6 is provided with a round Aopening to receive the'hinge pintles according to the invention.

The oven door is indicated generally by the numeral 3 and is preferably formed from a rigid metal 'casting having its edges upturned to form 10 a shallow dish-shaped frame, the upturned edges of' one corner of which are yindicated in the drawing by the numerals 9 and I0. The edge I0 is provided with a 'slot to allow the arm 3 to extend therethrough. Welded or otherwise fase 15 tened to the edge III and to the bottom wall of the door 8 is a metal bracket I I having the formation as shown in detail in Fig. 5. As shown clearly in Figs. 1 and 5 this bracket 'is provided with an upturned flange I2 which is welded to the edge I0 o1' the door frame, and also with an ojo upturned flange I3 which is welded to the edge l with-a right-angled ilange I9a having a threaded 30 opening 20 to receive a screw 2|, (Figs. 3 and 5), for fastening the sheet metal cover plate 22 in place. It is understood of course that the draw-,.- ing shows only one corner of the door and that brackets similar to bracketl I I are provided at the 35 three .remaining corners so that 'the cover plate 22 may be firmly screwed to the door frame.

For the purpose of limiting the extent of opening of the door to a substantially horizontal position, there is provided a' curved hangerand latch 40 member 23 at each side of the door. As shown e more clearly in Figs. 1 and 2 the member 23 is formed with a substantially circular shaped body portion terminating at its upper end in a latching projection 24 which is adapted to engage the 45 frame I to limit the downward opening movement of the door, and forthis purpose the' said frame member Ils provided with a slot 25 through which the latch member passes. Member 23 is provided at its lower end with a circularopening adapted 50 to he in alignment with the opening I8 for the purpose of receiving the hinge pintle I9 as shown more clearly in Fig. 1. Member 23 is also formed with an offset arm 26 having an opening in its forward end in ent with they opening I6 and 55 pintles are arranged to be assembled so that the portions 21 and 28 are in alignment, but preferably the portion 28 is slightly longer than the corresponding portion 21 so that when the pintles are assembled as 'shown in Fig. 1 the portion 28 partially overlies the portion 21. As will be clear from the showing of Fig. 1 the pintles are lo'cked against side-wise movement by engagement with 4 the vertical part 29 of the flange I9. As an additional precaution against dislocation of the pintles the bracket I I is formed with an upright flange 30 which together with the flange 29 defines a locking 'channel of about the same'width as the pintle portion 28. The pintles are locked against rotation by reason of the cover plate 22, when the latter is fastened in place on the oven door frame by screws 2 I.

In order to hold the door tightly closed 4there may be provided a tension spring 3I anchored at its lower end to the frame of the stove, and coupled at its upper end to the latch member 23 as shown in Fig. 2, it being understood that the parts are so proportioned that the doorA can remain in its horizontal open position against the tension of spring 3I. From the foregoing description it will be seen that there is provided a relatively simple hinge support for the oven door, and the only screws necessary to effect complete assembly of the hinge structure and door on the stove are the screws 2 which hold the cover plate 22 in place; Should it become necessary at any time to remove the door the removal can be effected very expeditiously since all that is necessary is to remove the screws 2l which are very easily accessible when the door is in ahorizontal open position. When the face plate 22 is removed, it is merely necessary to rotate the pintles I6 and I9 until they clear the flange I9 whereupon they may be easily removed without employing any special tools for the purpose.

While one particular embodiment has been illustrated and described, it will be understood that various changes and modifications may be made therein without departing from the spirit and scope of the invention.

What I claim is:

1. A supporting hinge structure for an oven door or the like, comprising a stationary frame member, a pair of arms projecting from said member each arm having a pintle receiving opening a pair of brackets fastened to at least two corners of the door each bracket having a pair of upturned lugs with pintle receiving openings, and another pair of lugs to form'a pintle locking channel, a plurality of pairs of right-angled pintles each of said pintles having part of -its length disposed in a locking channel, and a cover plate for the door to prevent dislocation of the pintles from said channels.

2. A supporting hinge structure for an oven door and the like, comprising a stationary frame, a pintle receiving arm projecting from said frame, a pair of pintle receiving lugs fastened to the door, a pair of right-angled pintles, a latch member having a pair of pintle receiving openings in alignment with the pintle receiving openings in said lugs, a locking channel carried by said door in which the opposed ends of the pintles are disposed to prevent sidewise movement thereof, and a cover plate for said door arranged to limit the rotational movement of said pintles.

3. A supporting hinge structure for an oven door and the like, comprising a stationary frame member, a pair of pintle receiving arms projecting from said member, a pair of brackets fastened to the door and each having a pair of lugs defining a channel a plurality of pairs of rightangled pintles each pintle having part of its length disposed in a channel to lock it against sidewise movement, a latch member slidably passing through a slot in said frame member, said latchv member having pintle receiving openings, and a. cover plate removably fastened to said door 4to lock said pintles against dislocation from said channels.

4. A supporting hinge structure for an oven door and the like, comprising a stationary frame member having a pintle receiving arm lxedly projecting therefrom, a bracket fastened to the door and having a pair of pintle receiving lugs disposed lengthwise along the side of the door, l
